Plantronics rates battery life as up to 7 hours talk time and 11 days standby time. The Voyager Legend UC comes with multiple charging options, including a case, desktop charging stand and modular wall charger.
It’s available in two editions: the Voyager Legend B235, for most UC (unified communications) systems including those by Avaya, Cisco, IBM, and Skype, and the B235-M, optimized for use with Microsoft Lync 2010 and Microsoft OCS 2007. Sadly, it does not come cheap: Plantronics’ MSRP is $200.
Wired or wireless headset for the desktop

All models in the series have detachable USB cables and Bluetooth, so you can use them with either a PC or mobile phone. You can even start a call with a wired connection and then unhook the cable to continue it untethered.
Plantronics offers two monaural versions (with a single over-the-ear cushion), the C710 and C710-M, and two stereo models (with two cushions)—the C720 and C720-M. As with the Voyager Legend, the C710 and C720 are designed for general UC use, while the C710-M and C720-M are optimized for Microsoft applications. The monaural models go for $130, the stereo versions for $150.
Speakerphone for the road

Plantronics’ Spokes software affords a range of call management features on top of the basic hardware controls for answering and ending calls, adjusting volume, and monitoring battery life.
The Calisto 620 comes with a USB charging cable and AC adapter. Plantronics says that fully charge, it supports up to 7 hours of talk time and 5 days of standby time.
Like the other products, the Calisto 620 is available in a general-purpose model (P620) and a version optimized for Microsoft apps (P620-M). Both have an MSRP of $150.
